Nuneaton,
in Warwickshire,
is a bellwether
where the Tories have a 4,882 majority and which was studied as the 'reason' for Ed Miliband losing in 2015. Seats like this are the ones Labour need to win in order to claim the keys to Number 10.

where barely a third of UKIP voters going blue would defeat Labour.
